Rybook may have a future in creative
I came in to shyt on this idea (especially the record breaking part) but it could have worked at least to a certain extent.
I would have extended it to 10 or so months though (night after Mania until night after Royal Rumble). Have Brock run thru him on his "last night with the company" on the night after Mania, and let him rock as a free agent and train for MMA or even go to NJPW to get some respek on his name then bring him back on the night after the Rumble as a serious ass kicker with a chip on his shoulder to interrupt Heyman's yearly "who's going to beat the beast promo".
It would take some real effort not to ruin the angle, but this could work with anybody. If nothing else it would bring some unpredictability back to wrestling which is sorely needed
